We currently have no "proofreading" section. All stories, once published, are there to stay unless deleted by a moderator. (Keep in mind, though, that you can always go back and edit the stories you've submitted.)
If you want a proofreader for grammatical errors, content, etc., I suggest you find a good friend or someone who's interested in your work to do it. You could e-mail them the story and they could reply with their advice. Once stories are submitted here, they're reviewed by me to make sure they contain no explicitly unacceptable material - such as child pornography scenes etc. - and then approved. I do not proofread for grammar and I don't correspond with authors unless it's about something negative in their story. I just don't have the time to be so connected with each and every author. Sorry about that
You could try posting in another Forum asking for ideas or hints, or even for someone to proofread. As for obtaining a "yaoi theme"...why not try reading some of the other stories or browsing through our galleries to get the picture of what's popular and common around here.
Once you're ready for submission, go to the Fiction Section and hit Submit. Copy/Paste/Type in your story and submit! I'll read it beforehand and, if approved, add it to our library. Please take note of which genre you'd like to submit your work to within the Fiction Section. Original Works is for stories you've written all by yourself with no outside characters, plot lines, etc. FanFiction is for stories you've written that do contain characters from outside sources or other outside information, plots, etc. The Communal Section is a hodgepodge of all different types. We're trying to phase out the C.S. and sort all stories into either O.W. or F.F.
Hope this helps!
